I use Oxford Street regularly both on buses and as a pedestrian. Pedestrians constantly run across the road in front of moving buses and even at pedestrian crossings ignore the red pedestrian lights. In some countries they would be fined for jaywalking.

It would be interesting to know how many accidents have occurred to pedestrians crossing Oxford Street when pedestrian lights are green.

As long as pedestrians take their lives into their own hands by not using green lights at pedestrian crossings accidents will continue, even if all vehicles are diverted.
